THE SENSOR DOES NOT 
GET MOUNTED TO THE 
WALL.  IT INSERTS INTO 
THE SAMPLE CHAMBER 
AND RESTS ON THE 4 

RUBBER BUMBERS.

   LIGHT SHIELD

THE LIGHT SHIELD IS USED 
TO PREVENT ALGAE 
GROWTH INSIDE THE 
SAMPLE CHAMBER.

NOTES:

-THE INSTRUMENT REQUIRES A MINIMUM OF 6 AND A MAXIMUM OF 

10 LITERS PER MINUTE CONSTANT FLOW.

-THE DRAIN MUST FLOW FREELY TO AN OPEN DRAIN.  ANY 
BACKPRESSURE MAY CAUSE THE SAMPLE CHAMBER TO 
OVERFLOW.

-THE HOSE BARBS MAY BE REMOVED FOR DIRECT PVC PIPE 
CONNECTIONS.

4.3 Sensor Mounting & Plumbing  

Locate the sensor as close to the sampling point as possible to reduce lag time. A site that 
is protected from the elements (sun, rain etc.) is preferred, but the sensor is rated for use 
under most outdoor conditions. The sample chamber is designed to be mounted with ¼” 
diameter bolts. The sensor does not get firmly mounted, but just sits on top of the sample 
pot. A light shield protects the clear sample pot cover & helps to prevent algae growth. 
Refer to the diagram below for mounting dimensions.
